The HMA-EMA RWD Catalogues are repositories of metadata collected from real-world data (RWD) sources and RWD studies. They are intended to help regulators, pharmaceutical companies and researchers to identify and use such data when investigating the use, safety and effectiveness of medicines.

The Catalogue of RWD sources replaced the ENCePP Resources Database, while the Catalogue of RWD studies replaced the EU PAS Register®. Additionally, Catalogues of institutions and networks are also available to support the RWD sources and RWD studies Catalogues. Together, these Catalogues offer an improved and more efficient service for researchers, regulators, and pharmaceutical companies to:

Facilitate the discoverability of adequate data sources to generate real-world evidence for regulatory purposes (e.g., identification of RWD data sources suitable for investigating a specific research question);
Aid in the suitability assessment of data sources by providing clear and easy access to information from the study protocol and study report;
Improve interoperability between studies and data sources;
Improve transparency.
